LiDAR
Laser distance sensing
LiDAR is a remote sensing technology that measures distances by firing laser pulses and timing their reflections.
The name comes from "light detection and ranging," modeled on radar.
LiDAR creates detailed three-dimensional maps of terrain, buildings, and objects.
It's essential to autonomous vehicles, archaeology, and topographic surveying: LiDAR revealed ancient ruins hidden beneath the jungle canopy.
